Bricked (?) ASUS Transformer Infinity TF700T

Hi there,
I need your help urgently.
I received a brand new TF700T and did make it work to support root.
I also did unlock the bootrom protection.
When I tried to install a custom ROM manager (Clockwork Mod) image from:here
The device didn't want to start any more - showing message:
The Device ist Unlocked.
Android cardhu-user bootloader <2.10 e> released by "TW_epad-9.4.5.22-20120615" A03
Checking for android ota recovery
Booting recovery kernel image
But nothing happens anymore (
I can wait for the battery to run empty in this mode.
There' no chance to boot from Micro SD.
The only thing what works at the moment is to connect the device via APX drivers.
I tried to communicate with device via NVFLASH tool
But when trying this - I get the message:
Nvflash started
Unknown Device found
Does any one have an idea where to find appropriate drivers for Nvflash?
Or the parameters to match TF700T?
Thanks in advance!

if you are able to access APX then you still have hope, first of all you need to push custom recovery like TWRP via fastboot mode and then install custom ROM. Most likelly you were to lazy to read a lot information on this forum how to install stuff properlly.
EDIT: if Tf700t has pin hole you should turn it off despite waiting for it to discharge...

I did already read a lot - for hours and nights.
But my main problem is: UNKNOWN DEVICE
What does TWRP mean? How do I get fastboot to work?
I'm even not allowed to enter recovery mode.
The device is just recognized as an APX -device...
I can't push or download any custom ROM since I can't communicate with the device in both directions...

For those who messed up really bad and can't boot but are unlocked.
EDIT: I didn't see that you are not unlocked. then you should Power on + volume down, wait, see two icons select wipe, pray to god it helped or not. And if it doesn't boot and you are not unlocked last thing to do is RMA.
You are not allowed to enter recovery because you have stock one with droid dead and red triangle I guess.This is TWRP site and all instructions are here TWRP - Team Win Recovery Project is alternative to ClockworkMod Recovery but better. to get to fast boot turn on your tab holding power on + volume down and then do nothing while it asks to pres up. if you are unlocked you will see 3 icons select usb drive icon. FASTBOOT mode. now follow instructions from TWRP site. after that youl need custom rom zip. if recovery instaled successfuly and you can get into it you'll need to put custom ro into microSD or if you can into internal storage. if you can't conect to pc via cable and start cmd if Windows or terminal if Linux or mac. type
Code:
adb shell
mount /dev/block/mmcblk1p1 /data/media
you will be able to access microSD via recovery (unless it is different than Prime tf201 you will need different command, but give it a try)

Thanks for advise - BUT
I have no choice like selecting Fastboot or USB etc. with volume buttons.
These options unfortunately do not come up anymore.
My device is definetly unlocked. It shows up "Device unlocked" when trying to boot normally.
When trying to go to recovery, with Volume - hold, the device tries to launch to recovery but hangs in status:
Device is Unlocked
Android cardhu-user bootloader (2.10 e) released by "TW_epad-9.4.5.22-20120615" A03

Booting recovery kernel.
I have NO option to go to fastboot! Only way will be APX but nvflas always tell me unknown device.
So I was looking for any other version of nvflash.
In other forum I did find hint for nvflash ICS but didn't find right version yet.
If I only could get communication via APX worked to my device, then I could send data via nvflash and APX...

I assume you can't even go to rom as it bootloops on EEE pad screen not on rom splash screen
1. Did you try Wipe option in (power + volume down, wait 5 sec.)? [it is esential in all situations of trying to recover]
2.ammm... when you enter "adb devices" in your cmd on PC doesn't it show anything (do it while your tablet is on and hangs anywhere, just make sure it is on)? list is empty? if not it shows your device with some random letters and numbers.
Try manually setting your pc. Download android SDK and all packages for Android 4.x then in Device Manager (Control panel) find your Tablet and update your driver to Android ADB interface (you can experiment, till your device is shown correctly via adb devices command).
But first of all make sure you do or did first step. it is common issue among Prime users so maybe it can help you.

I would like to exchange email-adresses to enhance communication.
You could also send email to [email protected]
I did try with button combination (power & + button) as well, but device did not wipe.
For now - I'm about to update Android SDK )
Hopefully this works to recognize my TF700T...

If you manage to unbrick please post the information back here it may be helpful to others.

How did you get your TF700 unlocked? Asus hasn't posted an unlock tool for it yet that I could find.

Unlock + Root was never a problem.
I managed it to unlock the device using the TF300T tool / link.
Boot loop was big problem.
I did raise RMA in the meantime. New device is on the way.
Thanks to all repliers.
I will keep off doing this again / wait until xda-experts will provide a working way to CWM TF700T.

My Transformer Infinity isn't bricked, I just can't get it to boot into recovery. (I'm unlocked and rooted, but no custom ROM.) I have tried both CWM and TWRP 2.2.0 with GooManager. The tablet just won't boot into recovery mode. I can hold the Down Volume key and Power button to have the initial boot up menu display. When I press the Up Volume button to boot into recovery mode, it just hangs like the OP talks about. I then have to hold the power button for about five or so seconds to get it to power down again. I can turn it back on and it will boot normally.
I thought maybe something was messed up because I installed busybox, or hacked the Flash Player to work in desktop mode, or tweaked the build.prop file or something. I've put the build.prop file back to default, and removed the busybox apps, but that hasn't resolved the problem. I've tried re-running the unlock tool, but it fails halfway through. I'm not sure if that's normal or not after you've run it once, or an indication of something messed up.
Any suggestions on what else to try or look at are appreciated.

UPDATE: I finally got TWRP 2.2.2.0 to work using the following option from the Instruction Page (http teamw.in/project/twrp2/105):
Download - ADB / Terminal method:
Download the above file. Save it to the root of your /sdcard directly (internal memory only) and rename it to twrp.blob
Launch terminal emulator or connect to your computer and open an adb shell, then type the following:
su
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4
Then reboot to complete installation.

Trying to flash the new CWM recovery, too. Mine gets stuck in the bootloader menu (where you have to choose between Wipe, fastboot mode, and cold startup). Every time I select fastboot it says "starting fastboot usb protocol" and just hangs there.

That is what it says when you are in fastboot mode, the rest of the job you do with a computer. Also we have had major issues with cwm on the Prime, I would recommend TWRP!

You flashed a PRIME rom to your tf300?

First of all, we should know which firmware do you have before your tablet doesn't boot (Stock ICS, JB, Custom Rom).
Then, you can use fastboot to recover your tablet (i did it a lot of times). Try steps below:
1. Download latest oficial Asus firmware (V10.4.2.13). BE SURE to download your region (WW, US, etc...)
2. Extract downloaded zip and take blob file.
3. Download Android SDK and install them on C:\ (http://developer.android.com/sdk/index.html)
4. Execute SDK downloader and mark tools and platform-tool options for download.
5. OPTIONAL add tools and platform-tool folder to PATH, after that test if fastboot command runs on CMD.
6 Copy blob file on same SDK folder.
7. Connect TF300T with usb cable and put it in Download Mode (USB icon on recovery menu)
8. Wait until drivers are installed.
7. Open CMD, go to Android SDK folder and then type command below:
fastboot -i 0x0B05 flash system blob
wait 2 or 3 minutes and then you'll see a message that send and write was OK. Now type this command:
fastboot -i 0x0B05 reboot
And It should boot again.

Yes, that's right, but I suppost if he tries to flash a custom rom he has already unlocked his device. You can't flash any rom without unlock bootloader.

I cant do anything apart from get on to apx mode, from apx mode how do I use command to flash back.
My tf300 is ics, unlock.
when i connect usb to pc. i press power and volume up. thats only things i can do.
so what do i do next?
thanks.

The same problem.
I only see: "device is unlocked" or something like that. And nothing go on.
Is it totaly bicked or is there any chance to restore it?
Please advice.

Did anybody ever figure this out. I'm in the same boat. Can't do vol down+power to get to recovery. But if i do volume up+power it shows in device manager as transformer prime apx interface (even though it's just a tf300)

no way to unbrick tf300t
Funny, I bricked my tf300t without doing anything. One day it just got stuck in asus screen.
tried to recover, nothing happended.
tried hard reset. Nothing.
Wipe data: result: bricked tablet.
I'm looking for information it is defintely impossible to unbrick it.
Anybody else with the same situation can tell you that.
Nobody has even been able to do it.
If you send it to Asus they provide a new tablet.
Conclusion:
TF300T is a terrible product, as any other asus product i assume. Amazing that you can brick a tablet without even trying to flash it or without even being connected to a computer.
It bricks by itself. Hundreds of other users can confirm it.
My advice: dont by asus products
If you already have one, dont use wipe data as anybody who has done it has ended up with an expensive useless brick.

Odp: [Q] How to unbrick my tf300
I don't agree witch this, only think what you not should use is t the wipe data from bootloader menu - I already flashed many times not working kernel, get really often bootloop - the problem is - much users going to made stupid things when the get a soft bootloop - If you get this first try wipe data from recovery, if this won't help, try to format data from recovery - often happends that the ext4 filessystem get broken. Recovery should allowa us to run fsck on data - I fixed my bootloops many times with it without loosing my data.

OP,
I think your anger is misdirected. The device, as it comes out of the box, works 100% without issues. YOU as a user decided to make changes that could potentially brick it. YOU chose to follow the steps with the full disclaimer that it can/may brick your device. So at the end of the day, its' not the fault of ASUS or the device for "bricking itself"; the responsibility of your actions lies on your own shoulders.
That being said, Asus will not provide warranty support for a tablet that has been unlocked. This is clearly stated in their unlocker app. So no, they won't "send you a new tablet" if you send it to them (unless you pay out of pocket for the repairs).
I've done just about as bad of a brick as I possibly can on my tablet and recovered just fine. It was just a matter of being CAREFUL, reading instructions three times before l followed them, and asking lots of questions. But what ultimately saved me was the NVFlash tool, and for that I am eternally grateful.
Just my two cents.

I have problem that my partitions won't mount at all. I have access to fastboot, CWM, and adb but no matter what i cannot access my partitions and so i cannot install zip from CWM. When i try blob within fastboot my tablet just freezes.....

Hi, what happens if I have no access to fastboot? It loops in the ASUS logo and what ever I do, can't gain access to recovery because it doesn't get into fastboot. So how to solve it via APX? Thank you.

You wont solve the problem unless youve done a nvflash backup. If you tablet is recognised as APX while plugged in PC, then you have an unrecoverable brick. If nothing appears when you plug it, then try on another PC.

Hi,
I am having a similar problem to the one described. I have unvblocked my TF300T and installed CWM recovery (v. 6.0.2.3), but it can't mount any filesystem, so I can not flash anything. The boot menu is gone (RCK, wipe tablet, android) and when I switch the tablet on It just goes to CWM. If I connect the tablet to a PC, I can send commands with adb from my win 7 PC (for instance "adb reboot" will reboot the tablet), but fastboot doesn't work (it keeps "waiting for device"). Prior to this my android version was JB 4.2. I didn't make any backup, so I am fearing the worst outcome. Did I brick my tablet for good?
Thanks a lot for any reply.

TF300T blocked on boot screen
hello everybody,

My Asus TF300t is blocked on boot screen after try to install a new rom on JB 4.2.2.

I read the previously posts and :

- i dowload the "blob" file and i placed it on tools directory
- but, the actually problem is whis the lign "fastboot -i OxOBO5.... (i have copied and paste it on schell command) and enter
load_file: could not allocate 820157833 bytes

can you help me please ?
i want to resolve this problem with you to install the best rom for this model.
Thank you very much and sorry for my english, i am french but i understand your paragraph.
See you soon

If you have mounting / PIT errors you could try my solution as described here:
http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
no guarantee though but it basically wipes your device so that you should be able to flash the blob file back.
also if your tab still is ICS- check if you are using the correct recovery - also bear in mind that cm10.1 afaik uses the new 4.2 bootloader and probably wont work with ics based PIT devices.

Hello man,
I try your method but the problem is the same when i want to copy the blob file, "not enough space ..."
fastboot erase system OK
fastboot erase recovery OK
fastboot erase userdata OK
fastboot erase boot OK
fastboot erase misc OK
fastboot erase cache OK
fastboot -i 0x0B05 flash system c:\adb\TF300t\blob PROBLEM
The message is the same like previously, always the problem of space.
I tries the method by copy the blob file on different directory on my computer and on a usb key too.
Always the same problem of space
I think the problem is the space on the tablet but i dont' understand. I erase system, recovery, userdata, boot, misc, cache, i think the tablet is empty.
Can you help me please ?
Thank you very much

which blob file did you use? Was the zip appropriate for your region? also what was the last stock rom version you ran - you said you wanted to update to 4.2.2 - what was the old version?

Help needed!!NVFlash Bricked my tf700t!

Hi all
I have tried to make my device brick proof using NVFlash metod. I have flashed the AndroidRoot bootloader:
fastboot -i 0x0b05 flash staging ebtblob.bin
I have AndroidRoot 9.4.5.30r01 on the screen after rebooting.
cant generate nvflash blob files with the
fastboot -i 0x0b05 boot nvfblobgen.img it gets stuck. (waited forever)
It would not boot up anymore. It would not get pass the first asus logo.
Fast boot and APX works. Cant get into recovery it gets stuck.
Anything i send to it over fastboot device gets stuck.
is there any way to get back to previous bootloader?
or is there any way to get it fixed?
thank you.

Have you tried downloading ASUS original firmware and put it on your microSD and recover from there.

That didn't work. It just goes to "booting recovery kernel image" and gets stuck.
is there any other way?

Which ROM are you running? The latest unofficial CM10 (by hiemanshu) requires the JB bootloader -- it wouldn't boot on my 700 with the AndroidRoot bootloader. There is a link to a simple how-to here:
http://forum.xda-developers.com/showpost.php?p=32647108&postcount=659
After you've tried that, please report back in.
Oh, and errrr, on my computer, the connection server is wonky. Try and give the commands to kill and restart the (adb) server -- that always starts functionality on my x64 Windows 7 machine):
adb kill-server
adb start-server

and any time I turn it on now with power button + volume down button it just goes automatically to "booting recovery kernel image" and hangs there forever. Cant even get options anymore to get to fast boot .

Sorry mate,but at this point you can't recover your device anymore,only Asus can fix that.

Shame you didn't try the kill/restart trick -- that might have given you the blobs you'd need to recover from this. I do not think there is an option to recover with adb/fastboot access, although you might try scrounging the forum and get a lucky hit. Otherwise, it's ASUS tech support for your device.

As long as your device is recognized in fastboot mode you have a high chance to recover but he can't get in fastboot anymore, so sending back to Asus it's all he can do.

I fully agree, and already said so -- but still it's a shame he didn't try to restart the adb server.

[Q] HELP! I think i bricked my TF700 while installing Jelly bean.

Hi All,
i have unlocked bootloader, Rooted ICS
now i installed the latest JB update via the SD card method (renaming it to E201_768_SDUPDATE).
did the power+vol down method. intstalled it and reboot.
now all i get is this message coming up.
"The Device is UnLocked.
Android cardhu-user bootloader <2.10 e> released by "US_epad-9.4.5.26-20120720" A03
Booting recovery kernel image"
and it gets stuck there at the ASUS screen.
i have tried to install the APX driver from universal driver 0.7 TF700, and all i get is unknown device in win7 device manager.
hence i cant get into NVflash or Fastboot.
is there anything else that i can do to unbrick this tablet.
are there any other drivers that i need to install in win7 x64 or it to recognize that it is an asus tablet.??

Looks like the JB update didn't write everything properly - you still have the old bootloader. You should really have created backups for nvflash before trying to upgrade to JB.
But it's still not too late. Can you switch yout device to fastboot mode? If yes, then it's just a matter of getting your PC configuration right.
Then the next thing I would do: re-flash some custom recovery via fastboot, make sure it works and you have adb root access, check if /sdcard is ok, then install the AndroidRoot bootloader to create your blobs for nvflash, reboot into recovery, pull the blobs to your PC via adb, and only then try to upgrade to JB again.

Hi, no unfortunately i cant access fastboot, i have tried using the TWRP method of and all i get it a message saying waiting for device. when i try to push the TWRP.blob file.
i think my problem is that the usb device drivers are not working hence win7 x64 cant recognize the tablet when it is turned off (APX mode i believe)

Let's check it step by step:
- On the device, can you still activate the fastboot mode (USB icon)?
- On your PC, you should see a USB device with vendor ID 0b05 and product ID 4daf. Should be visible somewhere in Device Manager under Windows, maybe someone else can give you details (under Linux everything is much simpler with lsusb).
- On the PC, "fastboot devices" should give you more than no output at all (some question marks, AFAIR).

And if you hold down Volume-down while powering on, it's the same? In that case, 3 icons should appear before it tries to start the recovery kernel.

You're done. You need to send out for repair. Sorry, but I haven't see any one here able to recover the device with the above message.

hmm bummer.. no other way to force install a device driver to detect the tablet on my win7 pc.? all i need is a glimmer of hope that i can still talk to the tablet at the lowest level interface. ie APX mode.

The driver on your PC is not the problem. For using nvflash in APX mode you'd need the Secure Boot Key, which is unique for each device and which Asus does not give us, or the blob for the wheelie tool that can be created with the AndroidBoot hacked bootloader, which is also unique for each device. But for creating this blob, you need working fastboot access.

Bricked my tf300t?

To sum everything up:
1. My rom didn't work so I decided to find a new one :good:
2. I read and understand that it's much easier using fastboot
3. I was flashing the official rom when the antivirus requested a reboot
4. I forgot the flashing, and just clicked on reboot :silly: :crying:
The screen remains black when I try to boot it up :crying:
The only sign of life is when I'm charging the light is lighting and "APX" is showing in the device manager on pc with a yellow triangle, I haven't understand what "APX" stand for yet so please explain
(My bootloader was unlocked and I flashed twrp 2.5.5 just before I did this)
Do you have any tips for me? Or is the device bricked and have to be sent for service?
Please help me :fingers-crossed:
Edit: This is wrong section I know, can anyone move it to the Q&A please?

Moved.

Apx is a method provided by the cpu manufacture for recovery. Due to the way asus has handled locking the unit apx is only available if nvflash is installed while on ICS (4.0).
Reset may be a good option for you. Power on unit. Hold volume down and insert a small paperclip to into into the reset hole. This may get you into the bootloader.
Reset: A small hole about 25mm or 1inch below the sdcard slot.
Note: If this fails you could do the same but hold volume up and hope.
Beyond this running the battery down has worked for some or remove the back cover and disconnect the battery. Leave it disconnected for thirty minutes, then reconnect.
Also see my signature for other methods to get into the bootloader. Don't bother with apx as it is useless for us.
We are looking for any change in the unit. With a change may come use of adb, fastboot, or recovery.
Try do each thing in turn and repeat this sequence twice more.

Thanks for the explanation and fir the tips! I'm going to try this

It doesn't seem that any of the following work, but I haven't tried the battery pull thing, because I see that it's a sticker over the cover that says that the warrenty is void if removed. If I send it for service will the guys know that I have unlocked it, and then void the warranty?

I understand. If still in warranty I wouldn't remove it either.
I'm sorry that is all I have for your situation.

Lads, let me join your conversation. I've almost same problem, probably different root cause, but same summary:
1. Originally I downloaded JB 4.2 from support.asus.com source
2. Tablet got reflashed & worked as normal, but I lost roots which I had earlier, therefore I decided to get root privs again.
3. So, I went into TWRP web-site & downloaded openrecovery-twrp-2.5.0.0-tf300tg-JB.blob blob file & via ADB was able to flash TWRP 2.5 onto my TF300T, but...
4. ...somehow TWRP doesn't let me to mount neither system, not SD-card, nothing. And currently
5. I think I'm bricked (& my TF300T too). When I press power button - tablet switches on & gets straight into TWRP, where I've only option to power it down or reboot TWRP tells me "are you sure? No OS installed".
6. When I try to switch tablet into bootload (with volume -) writing "The Device is Unlocked" shortly blinks slightly brighter, kind of trying to get into bootloader, but gets into TWRP anyway.
Any help, please! I know how Donate button works!
P.S. Because I very new writer (but really old reader) of XDA - I can't incert outside links...

Which tablet do you have? You show TF300T but using TF300TG twrp.
The bootloader changed again with 4.2 firmware and requires twrp especially for that version. I have been told the openrecovery-twrp-2.5.0.0-tf300t-4.2.blob does not work properly so you should have used openrecovery-twrp-2.4.4.0-tf300t-4.2.blob if you have a tf300t.
We need to break the cycle of going into twrp and only twrp.
Let's try to use twrp for that purpose. While in twrp select reboot while holding volume down.
If that fails to make a change while in twrp type adb reboot bootloader.
If that makes no change type fastboot -i 0x0B05 reboot-bootloader.
If there is still no change try the reset while holding volume down.
Reset: A small hole about 25mm or 1inch below the sdcard slot. Use a small paperclip to insert into the hole and press gently while holding volume down.

Dear Friend! :good: That what makes difference between you - old member & me - amatuer. Yes, I loaded ...TG version of TWRP onto my ..T tablet. Bad words aren't allowed in XDA forum, otherwise I'd call myself with proper name. Anyway,
I tried to reboot from TWRP, held volume - & had no success. It loaded into TWRP again.
Then tried to reboot with command adb reboot bootloader, as you mentioned - my Windows7 PC doesn't see tablet, showing Transformer with yellow ! sign. And I tried fastboot -i 0x0B05 reboot-bootloader command, ADB is saying <waiting for device> forever & nothing happens. so I stopped here so far, waiting for your advise...

Ok...
So, I bricked my tf300t. I ordered a new motherboard off ebay and replaced the bricked one. It works, but it was not factory reset and still has the owners info, etc. It is password protected. I don't know the pw. When I try to boot into the recovery console, I get a dead android. Going into the menu, I have an option to wipe or boot android. How do I get around this?

My suggestion is use stock recovery to replace the encrypted os (probably JB 4.2) with JB 4.1 (10.4.2.20). You can download here [INDEX]25 Apr 2013 - TF300T/TG WITH ALL ASUS ORIGINAL TOOLS-Firmwares-Kernels-Guides-. Look in firmware TF300T. Use the proper sku (ww, us, etc) for your country. Please give philos64 a thanks while there he spent much time creating that post, supporting the downloads, and updating.
Unzip the downloaded file once - rename to EP201_768_SDUPDATE.zip. Place the file on your internal sdcard if possible if not place on your micro sdcard. Boot into the recovery console and make the hungry android happy. This will probably take ten plus minutes.

Dear tobdaryl! Thanks very much for your advice, I had to dissapear for couple of days, so couldn't answer. I followed your link & had no success. When I power on TF300T & connect it to PC, it's being read as Transformer (see my 1st picture), unlike in the guide they are working with Asus Eee pad device (my 2nd picture), so when I'm trying to install drivers from un-zipped folder it says "...couldn't install drivers for your Transformer".

Tobdaryl, I couldn't find "Donate Me" button in your profile, so give me your paypal account for a little present please! :good: It worked!!! I installed correct driver from given guide, rebooted into bootloader, using ADB comand & got 3 icons: RCK, Android & Wipe Data. I tried Wipe Data, it said "can't mount something", don't remember now what. I rebooted again & clicked on Android & loaded into normal screen. Because of Asus became completely flat I put it on charge now. And after that I will have to come back to original task - to root my TF300T. While it's charging I downloaded Goo manager & tried to install TWRP, it said "No recoveries were found for your device", but in same time file for my device (that's where I made mistake, downloading TF300TG version) does exist, so what's story here? I guess this is may be because my TF300T isn't rooted yet?
Adding later. after digging this & other forums I found that in order to get root & have to have CWM/TWRP on my device & I can't get them until my TF300T is rooted. Am I confused & talking rubbish?
Adding 2 hours later. I rooted the device using XDA guide. Still trouble to reboot device. It always reboots into TWRP, then I have to connect it to PC & reboot with ADB commands. This isn't right...

Go manager does not have the proper twrp for our tablet.
Rooting is no longer required to flash twrp. Motochopper will root with just adb.
I suggest we try to get everything working properly with stock before changing or adding anything.
Go to to this link and download the stock Asus firmware 10.4.2.20. Choose the proper sku for your location (ww, us or whatever). Don't forget to thank philos64 while there. Unzip once and place on your tablet, flash with twrp, if that fails unzip again and place the blob file in the directory with adb and fastboot and flash with fastboot. Verify everything works properly before making any other changes.
Thank you for the donation offer.
I don't have a method to receive donations. A simple click on thanks will be good.

My problem is that because I installed wrong TWRP by mistake - it can't mount anything & I can't install anything from SD or internal memory. So, should I delete existing TWRP somehow &/or replace it by CWM recovery?

No don't delete twrp or install cwm. We should have access to adb and or fastboot. We should be able to use either to get sorted.

May I ask you then? My ROM number is: JOP40D.WW_epad-10.6.1.15.3-20130416 & as I can see from numbers you are offerring me to downgrade (from 4.2 to 4.1). Will this not kill the device? And why can't we re-install existing ROM through ADB? I'm not arguing, just trying to understand.
